Question

Identify the correct mirror image of the given figure along X-X' axis :

• A.

  

• B.

  

• C.

  

• D.

  

Hint:

The mirror X-X' is vertical, so the figure is reversed left to right while top and bottom stay in place: the open side of the C-shape must face left and the arrow-head must point right.

Answer 1

The Correct Option is A

The given figure is a C-shaped frame open towards the mirror (right side). The top arm carries a small two-cell block near its left end, the bottom arm carries a block of four cells (2 x 2) near its left end, a narrow two-cell strip stands inside near the right, and an arrow-head (chevron) points to the left.
A vertical mirror exchanges left and right only. In the image: the frame opens to the left with the solid side on the right; the two-cell block of the top arm and the four-cell block of the bottom arm move to the right end of their arms (top stays top, bottom stays bottom); the two-cell strip moves to the left side; the chevron points to the right.
Option (2) has the chevron pointing left, option (3) interchanges the top and bottom blocks, and option (4) is the unchanged figure. Option (1) satisfies every condition.
Answer: (1) the figure shown in option (1)
